Boston Express requires a photo I.D. for all passengers traveling with an adult ticket. We do not require identification for children under the age of 12 who are traveling with a parent or guardian. However, if they are traveling alone, they will need a school I.D., passport or a copy of their birth certificate. Children under the age of 17 with no photo I.D. must be accompanied by an adult with a photo I.D. upon purchasing the ticket. These are security measures that we take in the event that there is an emergency. This allows us to assist officials in identifying who traveled on a particular day. We do not generate passenger lists for each bus and therefore you are required to show your I.D. each time you travel. We do not store this information. If you have questions about acceptable forms of I.D. or special circumstances, please contact the Information Center at 1-800-639-8080 (TTY Relay: 711 or 1-800-735-2964).
